CARBON-BOOK. r

SPECIFICATION forming part of Letters Patent No. 573,871, dated December `29, 1896. Application filed March l1, 1896. Serial ITO.v 582,816. (No model.) y

To all whom, it 'nw/y concer/t:

Be it known that I, J FRANK GREEN, a @mzen of the United States, residing at Mansiield, in the county of Richland, State of Ohio, have invented certain new and usefulIm-' provements in Carbon-Books, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in carbon-books of that class in which provision is made for making two or three copies at one'and thesame time.

It has for its objects, among others, to provide a simple, cheap, and improved book of this character in which the book is made up of a series of leaves,`each set comprising three sheets, the intermediate one of which is a thin or tissue sheet, and a carbon-sheet having its carbon upon both sides, said carbon-sheet being secured at one end bya leather, cloth, or

paper hinge to a block held at the end of the leaves and adapted to be folded toward the i ing upon the top of` the book.

other end of the book and between the tissuesheet and the next lower or adjacent one. A carbon-sheet thus held cannot slip out of place or have any lateral motion and will fall into place almost automatically. The sheets are made up into a pad or tablet, having a lip at the bound end to iit into the clamp or clasp on the end of the coverin which the pad or tablet is detachably held in said clasp, the same consisting of a slightly-flexible metallic strip,

4bent into substantially V or U formin crosssection, and held Within the cover, so that the bottom of the book will be at with the bind- The block to which the carbon-sheet is attached being of substantially the same height as the binding, the book retains its normalthickness until the last leaf is removed, and I have found from experience that this construction also lengthens the life of the hinge or fold of the cover of the end adjacent to said block. A Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularlypointed out in the appended claim.

` The invention'is clearlyillustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this speciiication, and in which- Figure 1 is a perspective view of my iinproved book with the cover turned .back and the leaves of one set partially rolled up, and Fig. 2 is aiwvertical longitudinal section through the book with the cover shown as bent back under the bottom of the book and a tissue sheet which has been previously written upon turned back and held between the cover and the back of Athe book and also `showing the carbon-sheet in position after receivingan impression from the pencil tomake three copies.

Like letters of reference indicate like parts inboth the views. Referring now tothe details of the drawings by letter, Adesignates the back of the other suitable material one end of the carbonsheet C, which is provided with carbon upon both sides, as indicated in Fig. l, and which is of such a length that when doubled, as in` dicated in Fig. 2, it extends the entire length of the body portionof the leaves. The other end of the cover is extended vertically, as at a', and thence downwardly and toward the other end, as at a2, so as to form a sort of dovetailed recess or groove, in which the stub ends 4of the leaves are held.`

D is a plate of metal of some sufficientlyrigid material held within the back of the book at this end and following the bends o f the cover, as indicated clearly in Fig. 2. The plate being thus held within the back or inaterial thereof leaves the bottom of the book perfectly flat, and the end in whichV the plate is held is of substantially t-he same height as the block B, so that when the cover is turned over its free end rests upon the upper face of the inclined portion a2 of said end.

The leaves are bound in pad or tablet form, and each comprises a body portion and a stub. Any desired printing may be placed upon the leaves, and the arrangement of the leaves is novel. They are arranged in series of three,

IOO

the upper one E being of any desired style of paper, While the intermediate one F is of tissue or some analogous thin paper, While the other one Gr may be of the same character as the leaf E, or any other desired kind. The pad or tablet is removably yet securely held within the dovetailed recess or groove formed at the end of the book and in the temporary binder or clamp formed by the plate D and the end of the back.

In practice the cover isturned back, as indicated in Fig. 2, the carbon-sheet is placed between the leaves F and G, as seen in Fig. 2, and anything written upon the upper sheet E Will be by the double-faced carbon transferred to the sheets F and G. Thus three copies are made by the oneimpression and the carbon turned back and the sheets E and Gr removed, one going to the customer and the other to the wholesale house, Whilethetissue is left inthe book, although it will of course be understood that either of theI other leaves may be retained inthe book and the other two disposed. of as above.

It will be observed that by my construction the handling of flimsy carbon-paper isavoided, thecarbon being of double thickness and sufficiently stiff to retain its; original form, and being bound tothe block onthecover at the end,.as shown, prevents the soiling of the hands and keeps the. carbon in position where it is always wanted and ready for use. The hinge by which the carbon is attached tothe block is gummed, so that when one carbon is Worn out all that is necessary to do :is to tear it loose from the block and meisten the glue or muci-lage on the cloth hinge of another sheet of carbon and adjust it to the block, and when it dries and becomes hard it is again ready y sheet it can be readily seen and read from the upper side.

Modiltications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claimcas new, and desire to secure by Letters Patent, is

In a carbon-book, the combination oia back and coverhaving one end bent to formatemporaryl holder for the leaves, a, metall-ie strip held in the bends of said back, a block secured to the back at' its junction. with the cover, a carbon-sheet secured at one end to y said block, and a series; of leaves in sets of t11.re;e with the intermediate sheet of tissuepaper, said leaves being held by the temporary clamp formed at the end of the back;

l substantially as described'.

In testimony whereof Ik .ai-.tix my signature inr presence of two witnesses.
